The incarnation of Piaget’s virtuosity in the art of the ultra-thin since 1957, the Emperador cushion-shaped self-winding minute repeater attains a double record for thinness in its category: 4.8 mm for the calibre 1290P - despite its 407 components - and 9.4 mm for its 48mm-diameter cushion-shaped case. Housing the fourth major complication movement entirely developed, produced, decorated and assembled in-house, thanks to the twin expertise of Piaget's two Manufactures, this exceptional watch meets a threefold objective: uncompromising technical mastery, the finest acoustics, and aesthetics focused on exceptional finishes. A dazzling showcase of the skills that Piaget has refined over the last 140 years, diamonds light up this gem-set version with all their eternal brilliance. This movement combining all the superlatives is revealed here in a display of fascinating transparency, enhanced by the very purest of diamonds. Its sapphire dial reflects the bewitching beauty of the precious stones and unveils in translucent splendour a movement enhanced by painstakingly hand-filed decorations. Master watchmakers, case designers and gem-setters have worked in unison to create an High Jewellery minute-repeater watch while conserving the exceptional acoustic qualities of the case, crafted in 18K white gold. With its contemporary-looking contours carved out amid an enchanting flourish of diamonds, the case of this luxury timepiece is a veritable masterpiece of gem-setting in its own right. No fewer than 332 diamonds of a variety of shapes – baguette-cut, round and emerald-cut – work their magic between the bezel, case-middle, lugs and crown, while 26 brilliant-cut diamonds adorn the buckle of its black alligator strap.
